Frequently asked questions

Which After Effects versions does UnMult support?

UnMult supports After Effects 2025, 2024, 2023, 2022 and 2021. The same five version numbers apply to Adobe Media Encoder and Premiere Pro, so the plugin covers the 2021 through 2025 releases across all three applications. If you're running a version within that range, UnMult is listed as compatible. For anything outside those years, check the developer's page, since compatibility beyond the listed releases isn't stated here.

Does UnMult run in Premiere Pro and Media Encoder too?

UnMult isn't limited to After Effects. It also runs in Adobe Premiere Pro and Media Encoder, each supported in their 2025, 2024, 2023, 2022 and 2021 versions. That gives the plugin the same version coverage across all three Adobe applications. Its function stays the same throughout: removing black to add an alpha channel to a lighting effect. For details on using it within each host, the developer's page is the place to look.

Is UnMult free to download?

UnMult is listed as free in this catalog. Pricing and licensing can change over time, so for the current terms it's best to check the developer's page on aescripts directly before downloading. That page also carries the plugin's version history and a demo video. Listing it as free here reflects how it's cataloged rather than a guarantee of future licensing, so confirming on the source is the reliable route.

What changed in UnMult version 1.2?

UnMult version 1.2 was released on August 27, 2025, and it marks the first version of the plugin posted to aescripts. Because it's the initial release on that platform, there's no earlier aescripts version to compare it against. For the fullest and most current changelog, the developer's page keeps the version history. Version 1.2 is the release documented here, alongside compatibility with the 2021 through 2025 Adobe applications.
